Abstract
In one aspect, ultrasound transducers are described herein comprising acoustic lenses having enhanced wear resistance. Such transducers can be employed in applications having harsh operating conditions, including veterinary applications. A transducer described herein, in some embodiments, comprises a polymeric acoustic lens having an acoustic velocity greater than 1.7 mm/μs, the polymeric acoustic lens arranged over an array of transducer elements wherein the array of transducer elements has a curvature in an elevation plane sufficient to compensate for wave refraction induced by the acoustic velocity of the polymeric acoustic lens to provide elevation focusing of an ultrasound beam generated by the transducer element array.
